I have a small pile of 1/2-to-1-inch thick pieces of irregularly-
shaped slabs of marble and slate, lovingly harvested from scrap piles
of marble and slate quarries in Vermont on various vacations :-)

I got the idea of making appetizers like small thick-crust pizzas or
quiches or stuffed rolls baked on these pieces and shaped like them.
Even serve them "on the rocks" in, say, small baskets, so that the
rocks would help keep them warm.

We bake pizzas on stones or tiles OK, right? Anyone know if marble
and slate will survive a ride in the oven at baking temperatures?
(Gently preheated, of course.)
